我国目前在马铃薯生产中防止马铃薯退化主要是采用二季作留种、夏播留种(秋播留种)、株系选种、实生薯留种等方法。1972年以来,吉林农业大学、黑龙江省农科院克山农科所等单位,利用马铃薯茎尖组织方法生产出30多个无病毒品种,已在十几个省市示范推广。马铃薯茎尖组织培养在我国是一项新技术。因此,有必要把茎尖组织培养技术与目前生产中广泛应用的主要留种
At present, the prevention of potato degeneration in potato production in our country mainly uses two seasons as remaining species, summer sowing species (autumn sowing), selection of strains, and natural seed keeping. Since 1972, Jilin Agricultural University, Keshan Agricultural Science Institute of Heilongjiang Academy of Agricultural Sciences and other units, the use of potato shoot tips tissue method to produce more than 30 virus-free varieties, has been in more than 10 provinces and cities model promotion. Potato shoot tip tissue culture is a new technology in our country. Therefore, it is necessary to integrate the shoot tip tissue culture technology with the main remaining species widely used in the current production
